1. Partially collapsed radicular cyst at tooth 26

A well defined unilocular radiolucent entity with a sclerotic periphery is present in the apical region of tooth 26. This entity has displaced the sinus floor superiorly, and has produced a dehiscence in the sinus floor. This radiographic appearance is consistent with the presence of a self-marsupialized radicular cyst in the periapical region of tooth 26. The sclerotic periphery of the lesion and its undulating shape is supportive of this diagnosis. Surgical recharge of the cyst landing appears to be indicated, and retreatment of the tooth may be required.

2. Extruded endodontic filling material at tooth 26P

Endodontic filling material has been extruded through the apical foramen of the palatal root of tooth 26. This material is located within the lumen of the marsupialized radicular cyst. The palatal root apex of the tooth appears to be the epicenter of the cystic lesion. The existing obturation in the mesiobuccal root of tooth 26 is laterally positioned, which may be suggestive of the presence of an unobturated MB2 canal. However, no pathology is present in the apical region of the mesiobuccal root.

3. Secondarily affected tooth 27

The cystic lesion originating at tooth 26 extends into the apical region of tooth 27. However, the apical foramen of tooth 27 do not appear to be involved, which suggests that this tooth is secondarily affected by the lesion originating at tooth 26.

4. Mild left maxillary sinus mucositis

Mild mucositis is present on the floor and walls of the left maxillary sinus. This is a non-significant incidental finding. The walls of the left maxillary sinus are thickened and sclerotic, which is suggestive of a history of sinus pathology. The sinus osteum is enlarged.
